Title (EN) CORDIERITE-FORMING BATCH MATERIALS AND METHODS OF USING THE SAME
(FR) MATERIAUX DE FOURNEE FORMANT DE LA CORDIERITE ET PROCEDES D'UTILISATION ASSOCIES
Abstract: front page image
(EN)The present disclosure relates to cordierite-forming batch materials and methods of using the same, and in particular batch materials for forming porous cordierite bodies suitable for treating engine emissions. The batch materials include sources of magnesium, alumina, silica, and high BET specific surface area raw kaolin clay. In some embodiments, the BET specific surface area of the raw kaolin clay is greater than 22 m2/g. In other embodiments, the BET specific surface area of the raw kaolin clay is greater than 13 m2/g, and the source of magnesium oxide and the source of non-kaolin clay source of silica both have relatively coarse particle size.
(FR)L'invention concerne des matériaux de fournée formant de la cordiérite ainsi que des procédés d'utilisation associés. L'invention concerne en particulier des matériaux de fournée destinés à former des corps de cordiérite poreux utilisés dans le traitement des émissions de moteur. Les matériaux selon l'invention contiennent des sources de magnésium, d'alumine, de silice et d'argile de kaolin brute à surface spécifique BET élevée. Dans certains modes de réalisation, la surface spécifique BET de l'argile de kaolin brute est supérieure à 22 m2/g. Dans d'autres modes de réalisation, la surface spécifique BET de l'argile de kaolin brute est supérieure à 13 m2/g, et la source d'oxyde de magnésium et la source d'argile non-kaolin source de silice présentent toutes deux une taille de particules relativement grossière.
